Correltion between magnetic resonance imaging and arthroscopic findings in patients with anterior cruciate injuries

The stabilizing anterior cruciate ligament prevents anterior translation and abnormal internal rotation of the tibia during standing and walking. Its disruption lead to loss of stability and potential significant dysfunction. This work was performed to evaluate the role of MRI in diagnosis of ACL injuries. This study was carried out on 50 patients with anterior cruciate ligaments injuries. They were classified into acute and chronic tears according to the time interval between injury and time of examination. All were examined by Magnetic Resonance Imaging [MRI] and by knee arthroscopy. A variety of MR signs were encountered and were classified into primary and secondary signs. Correlation of MR findings with arthroscopic findings was done revealing sensitivity, specificity, and accuracy of MR to be 88.8%, 50%, 81.8%. Accordingly, MRI is a non invasive reliable and versatile method of ACL tears assessment with a good sensitivity

Guided wire localization of non-palpable breast lesions

The wide use of screening mammography had resulted in the discovery of an increasing number of suspicious non-palpable breast lesions for which surgical excision after guided wire localization is the diagnostic gold standard. This study had included 32 patients with non-palpable breast lesions, wire localization was done guided by U.S in 22 patients and by mammography in the remaining ten. This was followed by operative excision of the lesion around the guide wire tip. Specimen radiography was done for 25 of excised specimens. Complete excision was achieved in 22 patients [88%]. Histopathological examination yielded the final pathological diagnosis, malignant lesions were found in 7 occasions [21.87%]. U.S proved to be a simple technique allowing guidance in different sites of the breast through the shortest possible route thus obviating excessive breast dissection

Study of pancreatic size in patients with different types of diabetes

There had been contineous evolution in the understanding of etiology, pathogenesis and complications of diabetes since its discovery. Insulin is secreted by the B-cells of islets of Langnhan's and in IDDM there is marked reduction in the content of B-cells while in NIDDM, there is considerable reduction of its mass. The aim of this work was to study changes in pancreatic size in diabetic patients as detected by both U/S and CT studies. It was noted that there is considerable reduction in pancreatic size in those patients of IDDM group, while in NIDDM patients the size reduction was less marked and it was evident more in those under insulin therapy than those controled by oral hypoglycaemic drugs. The head was less affected than the body in NIDDM patients while in IDDM all segments were affected
